FUNNEL.

SPECIFICATION forming part of Letters Patent No. 539,965, dated May 28, 1895.

Application filed December 9, 1893-' Serial No. 493,202. (No model.)

To Mr? whom it may concern:

Be it known that I, HERMAN STRATER, a citizen of the United States, residing at Boston,

. in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Funnels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to' make and use the same,

mouth piece, and a layer or mass of solder in' the bottom of the shoulder for the purpose of stiifening and strengthening the shoulder and securing the spout in position, as will be more fully described hereinafter.

The objects of my invention are to provide a shoulder on the lower portion of the mouth piece, and which extends at an angle to the mouth of the vessel being. filled, and forms a support for the funnel; and to strengthen and stiifen this shoulder at the same time that the spout is secured in place.

This invention furthermore may be considered as relating to an improvement upon that shown and described in patent granted to me on December 5, 1893, No. 509,966.

The object of my present invention is to simplify the construction, enable the article to be made more cheaply, and increase its durability. V i

The drawings represent, in Figure 1, a side elevation. Fig. 2 is a vertical diametrical section of afunnel embodying my invention. Fig. 3 is an inverted plan. Fig. 4 shows a modified funnel, the spout being longitudinally ribbed or grooved to form air-passages. Fig. 5 is a modified construction of funnel. Fig. -6 is a modified form of shoulder.

Funnels of the above class comprise two principal parts, a mouth-piece or liquid reupon the under sidein order to create passages for the air, which is expelled from the bottle as the act of filling progresses.

My present improvement relates particu larly to the change in the form of the funnel with respect to the collar, whereby said collar is incorporated to form a portion of the funnel at the base of the mouthpiece proper and further is made to perform the same duties as the said removable collar.

In the drawingsil have shown a funnel composed of the mouthpiece 2 which may be cup was moreover formed with ribs or projections shaped or frusto-conical in form and to be united with a spout 3, whichlatter may be a short length of pipe cylindrical, as shown in Figs. 1 and 2, or tapered as in Fig; 4. In the construction of funnels of this class a very important feature is to provide for ready escape of the air from the receiving vessel otherwise liquid is carried over and waste occurs. Furthermore it is important that the funnel should likewise set firmly upon the nose of the receiving flask or bottle and not be liable to tip thus serving as a rest for the nozzle of the supply vessel. To accomplish these objects and at the same time tosimplify the consruction, I propose to form the mouthpiece with a shoulder 4. This is located at the base of said mouthpiece and is formed as an integral part thereof as shown in Fig. 2 in section. Hence a fiat, or partially rounded surface may be created transversely of the spout at this point and such surface serves as a seat to support the funnel upon the nose of the vessel in process of filling.

To prevent the loss of liquid and to allow the air free vent from the bottle in process of filling I have formed radial corrugations 5 which may be of any desired shape in crosssection. Said corrugations are struck up from the metal forming the shoulder, the latter in thepresent instance being a part of the mouthpiece and create air-passages 10. Said mouth- I oo structed or destroyed; while a "stiff joint is created at the point of union between the spout'and the mouth-piece. Moreover the chance of b e k n hrou he. thin metal ermies the ed e he eethiee e: r meved, n e it an eetee w t h ee of the bottle, when actively employed.

When the funnel is placed in a flask or bpt;

In Fig. 5 I have shown an evident alternative, form of construction, that is in lieu of molding the shoulder from the material composing the mouth-piece as shown in Figs. 1, 2 and 3, I spin or draw out the metal at the upper extremity of the spout 32 in order to create a shoulder 42 and then unite the mouthpiece the reto 7 Since the air passages are formed upon the under surface of said shoulder "it 'is evident the'sarne results are obtained.
